"Notwithstanding any other provision of Oregon law, a parent who is eligible for and receiving cash payments under ORS 412.001 to 412.069 and 418.647, the general assistance program as provided in ORS chapter 411 or a general assistance program of another state or tribe, the Oregon Supplemental Income Program or the federal Supplemental Security Income Program shall be rebuttably presumed unable to pay child support and a child support obligation does not accrue unless the presumption is rebutted."

2.In light of the basis of our decision, we need not determine the proper relationship between ORS 25.245, which specifies the process by which an obligor can invoke the rebuttable presumption regarding the obligor's inability to pay child support, and ORS 25.405, which specifies the grounds on which to challenge an income-withholding order.
